Rs 4 crore = Rs 3 crore The difference between the sales in 2003 and 2004 = Rs 7 crore ? Rs 6 crore = Rs 1 crore The difference between the sales in 2004 and 2005 = Rs 10 crore ? Rs 6 crore = Rs 4 crore The difference between the sales in 2005 and 2006 = Rs 10 crore ? Rs 8 crore = Rs 2 crore Therefore, in year 2005 the difference between the sales as compared to its previous year was the greatest.
